AI Technical Summary
Traditional optical imaging systems struggle to achieve high-quality imaging over large fields of view, particularly in terms of controlling the principal ray angle and minimizing optical distortion. Furthermore, the need for multiple optical components increases system complexity.
An imaging system employing a combination of aperture and metasurface elements achieves zero or near-zero principal ray focusing on the image sensor by placing apertures and metasurface layers on a substrate, using the apertures to limit the lateral range of light and applying a specified angle deflection through the metasurface layers.
It achieves high-quality imaging over a large field of view, reduces the complexity of the optical system, improves the telecentricity and optical performance of the imaging system, and reduces the bandwidth requirements of the optical filter.
